Jeremy Clarkson quit 'The Grand Tour' because he had run out of ideas for the show.
The 63-year-old presenter and his co-hosts Richard Hammond and James May have filmed the final two episodes of the Amazon Prime car series and Clarkson admits that it was becoming increasingly difficult to come up with new automotive adventures for the trio.
He told The Times newspaper: "I've driven cars higher than anyone else and further north than anyone else. We've done everything you can do with a car. When we had meetings about what to do next, people just threw their arms in the air."
Clarkson added that the physical demands of the show had become challenging to cope with as he is "unfit and fat and old".
The former 'Top Gear' host quipped: "If you're Bear Grylls you go to a hotel – there aren't any hotels in the Sahara desert."
May has suggested that the chemistry between the presenting trio – who began working together on the BBC's 'Top Gear' in 2003 – was "fuelled by mutual loathing" but Clarkson disagrees with the assessment.
He said: "We've spent more time in each other's company than our families' over the last 25 years so I don't think it would have lasted as long as it did if we'd hated each other as much as James likes to think."
Clarkson believes that the rise of electric cars means that 'The Grand Tour' is ending at the right time.
He explained: "James May thinks there's never been a more interesting time for how we move around and he's probably right, but I don't think it's very interesting television.
"An electric car is no different from a chest freezer or a microwave oven. There's no glamour or excitement. This week on Top Chest Freezer! I think it suits the written media more."
